Designing a secure customer-facing analytics app requires a 3-tier serving architecture with per-tenant isolation. This approach validates connection and query strategies, using database namespaces or service-account boundaries to safely route backend queries for external users.

The best way to isolate tenants in a DuckDB SQL embedded BI architecture is through per-customer database namespaces or service-account boundaries. This enforces safe serving patterns and read scaling posture rather than relying on unsafe shared-database shortcuts.

Setting up API routing for external users in a MotherDuck production architecture involves defining a backend routing strategy that selects the correct connection per tenant. This ensures queries are validated and aligned with read scaling and consistency expectations.

Using a shared database for multi-tenant customer analytics is not recommended. A 3-tier pattern provides the necessary per-tenant isolation and validates query serving requirements, avoiding the safety risks and read scaling limitations of shared-database shortcuts.

Building a production-ready embedded analytics backend involves inspecting your live workspace, producing an isolation model, drafting an API contract outline, and creating a rollout plan. This orchestrates discovery, modeling, ingestion, querying, and connection selection.
